It fooled sorcery's incorrect check for sourceMappingURL into thinking
it had a source map.
Also up the error stack trace limit to 1000 to help future error
reporting.
* Improve error message
* Remove `SupportedExpressionWithTypeArguments` type; just check that the expression of each `ExpressionWithTypeArguments` is an `EntityNameExpression`.
* Fix bug
* Fix#10083 - allowSyntheticDefaultImports alters getExternalModuleMember (#10096)
* Use recursion, and fix error for undefined node
* Rename function
* Fix lint error
* Narrowing type parameter intersects w/narrowed types
This makes sure that a union type that includes a type parameter is
still usable as the actual type that the type guard narrows to.
* Don't allow ".d.ts" extension in an import either.
* Add a helper function `getOrUpdateProperty` to prevent unprotected access to Maps.
* Limit type guards as assertions to incomplete types in loops
* Accept new baselines
* Fix linting error
* Allow JS multiple declarations of ctor properties
When a property is declared in the constructor and on the prototype of
an ES6 class, the property's symbol is discarded in favour of the
method's symbol. That because the usual use for this pattern is to bind
an instance function: `this.m = this.m.bind(this)`. In this case the
type you want really is the method's type.
* Use {} type facts for unconstrained type params
Previously it was using TypeFacts.All. But the constraint of an
unconstrained type parameter is actually {}.
* Fix newline lint
* Test that declares conflicting method first

* Emit more efficient/concise "empty" ES6 ctor
When there are property assignments in a the class body of an inheriting
class, tsc current emit the following compilation:
```ts
class Foo extends Bar {
public foo = 1;
}
```
```js
class Foo extends Bar {
constructor(…args) {
super(…args);
this.foo = 1;
}
}
```
This introduces an unneeded local variable and might force a reification
of the `arguments` object (or otherwise reify the arguments into an
array).
This is particularly bad when that output is fed into another transpiler
like Babel. In Babel, you get something like this today:
```js
var Foo = (function (_Bar) {
_inherits(Foo, _Bar);
function Foo() {
_classCallCheck(this, Foo);
for (var _len = arguments.length, args = Array(_len), _key = 0; _key < _len; _key++) {
args[_key] = arguments[_key];
}
_Bar.call.apply(_Bar, [this].concat(args));
this.foo = 1;
}
return Foo;
})(Bar);
```
This causes a lot of needless work/allocations and some very strange
code (`.call.apply` o_0).
Admittedly, this is not strictly tsc’s problem; it could have done a
deeper analysis of the code and optimized out the extra dance. However,
tsc could also have emitted this simpler, more concise and semantically
equivalent code in the first place:
```js
class Foo extends Bar {
constructor() {
super(…arguments);
this.foo = 1;
}
}
```
Which compiles into the following in Babel:
```js
var Foo = (function (_Bar) {
_inherits(Foo, _Bar);
function Foo() {
_classCallCheck(this, Foo);
_Bar.apply(this, arguments);
this.foo = 1;
}
return Foo;
})(Bar);
```
Which is well-optimized (today) in most engines and much less confusing
to read.
As far as I can tell, the proposed compilation has exactly the same
semantics as before.
